Summary

Charter Communications

United States of America · AI-generated

residential cable spectrum access

The AS handle CHARTER-40294-DC is held by Charter Communications LLC.

What it's used for

  • The address space carries Spectrum residential and business access traffic, evidenced by reverse DNS entries like syn-098-007-144-000.inf.spectrum.com and netnames RRNY and CC04.
  • The AS announces 38,912 IPv4 addresses across 16 prefixes and 2 IPv6 prefixes, while maintaining only 2 observed neighbours, a ratio characteristic of a large access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for Spectrum Internet, TV, and Voice services, as well as internal infrastructure endpoints for the cable operator.

Notable

  • Registrants align with the announcer, listing both Charter Communications Inc and Charter Communications LLC for the various prefixes.
  • The inventory is split between the 98.7.128.0/18 block and numerous smaller 47.43.x.x blocks, reflecting the integration of legacy Time Warner Cable address space into the Charter estate.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,771 prefixes, as published 2026-10-15. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
